Title: Antenna angle error signal detection sensitivity correction circuit for automatically tracking satellite
Inventor: OKAMOTO HIROSHI
IPC: H04B7/15
Filed: 1987-10-30
Abstract: PURPOSE:To maintain a better angle error signal detection sensitivity even with a low S/N ratio by detecting the amount of noise in a base band signal outputted from a receiver for the demodulation of data to correct the sensitivity according to the amount detected. CONSTITUTION:A flip flop 4 is supplied with a sampling timing (e) from a timing generator 8 as generated at a peak point position of a full-wave rectifier output signal (c) and when a square data (d) is inputted, an output of the flip flop is turned to a high level and when an output of a comparator 2 is at a low level, the low level is latched and outputted. Therefore, the more a noise level overlapping a demodulation base band signal (a) increases with a drop in S/N ratio, the more frequently the FF 4 latches the low level. A constant current circuit 5 generates a different value of current (g) according to a high or low level of the output (f) of the FF 4 to be outputted to an LPF 6. In other words, the current (g) is averaged with the LPF 6 having a proper time constant to obtain a signal (h) for correction. Base on a value of the signal (h), an amplification factor of an amplifier 7 is variably controlled to correct a detection sensitivity of an angle error signal, thereby obtaining a fixed correction angle error signal.

Abstract: PURPOSE:To obtain pictures with excellent S/N without increasing circuit scale, by not including parts where no picture information exists of two-dimensional frequency areas of horizontal frequencies and time frequencies in luminance signals separated at the time of still pictures. CONSTITUTION:Chrominance components separated by means of a subtractor 25 by using the difference in the input and output of an one-frame memory 2 are multiplied by 1/2 by a constance multiplier 26 and supplied to a delay circuit 8. The chrominance components CF which are adjusted in delaying quantity by the delay circuit 8 are supplied to a mixer 10. Then chrominance components are separated by means of another subtractor 28 by using the difference in the input and output of an one-H delay circuit and supplied to a BPF 7 after they are multiplied by 1/2 by a constant multiplier 29. The chrominance components CL whose band in the horizontal direction is restricted by the BPF 7 are supplied to the mixer 10. Therefore, the chrominance components CF and CL are respectively outputted from the mixer 10 at the time of still pictures (k=0) and moving pictures (K=1). By subtracting the output C' of the mixer 10 from composite color TV signals by means of a subtractor 11, luminance signals Y are fetched and outputted to a luminance signal output terminal 12.

IPC: H01L21/3205
Filed: 1997-10-08
Abstract: PROBLEM TO BE SOLVED: To prevent the parasitic capacitance of a semiconductor device from increasing, even when a dummy pattern is used and eliminate the increase in the number of pattern correcting times which increases due to the existence of the dummy pattern. SOLUTION: A semiconductor device is provided with wirings formed on a semiconductor substrate and an inter-layer insulating film which is formed on the entire surface of the semiconductor substrate carrying the wiring and has a planarized upper surface. The wiring has a dummy pattern 5 which is formed so that the distance between the pattern 5 and a line 4 used as a signal line becomes 3-200 μm. When the wiring interval is set to >=3 μm, the parasitic capacitance of the semiconductor device can be ignored, and the operating speed of the device does not become slower.  In addition, since the dummy pattern 5 can sufficiently exert a planarizing effect, even if the pattern 5 is separated from the wiring pattern by about 200 μm, the correction for the pattern 5 is not required, and the layout of the semiconductor device becomes easier even when the pattern of another layer is corrected.

Abstract: PURPOSE:To improve the patterning accuracy of a resist film, by using a mask wherein a part which is yielded because a light source has a specified size and in which the width of the light sensitive region of a resist film is changed is corrected by the width of a mask pattern, in addition to correction for position deviation. CONSTITUTION:The patterns at the central parts of a mask pattern 7 and a resist pattern 8 are made to be 7a and 8a, respectively. The resist pattern 8 is formed by patterning a resist film 2 by transferring the mask pattern 7. The patterns at the peripheral parts are made to be 7b and 8b. The width of the patterns 7a, 8a, 7b and 8b are made to be W3, w3, W4 and w4. The center of the pattern 7a agrees with that of the pattern whose half-shade blur is not corrected. The center of the pattern 7b is moved to the inside. The sizes are expressed by W3<W1 and W4<W2 (where W1 and W2 are the widths of the patterns whose half-shade blurs are not corrected) and by (W2-W4)>(W1-W2). The difference makes w4 and w4 approximately equal to W1 and W2. Thus the patterning accuracy of the resist film can be enhanced in the exposure using a light source 1 having the specified size.
